    16  * The HTML API aims to operate in compliance with the HTML5

    17  * specification, but does not implement the full specification.

    18  * In cases where it lacks support it should not cause breakage

    19  * or unexpected behavior. In the cases where it recognizes that

    20  * it cannot proceed, this class is used to abort from any

    21  * operation and signify that the given HTML cannot be processed.
